Fiber Glass

Production of fiberglass is dominated by C-glass and E-glass production. C-glass is also known as “wool” glass and is used in the production of insulation for construction. E-glass has many applications in areas such as aviation, boating, automobiles, and telecommunications. Both of these types of glass require very high temperatures to melt the glass and consist of corrosive elements that attack the refractory lining.

Due to this harsh environment, the highest quality of refractories is required. Chrome-alumina materials are the most common types of refractories used in the melting of fiberglass. Chrome-alumina refractories vary in chromia content from 10 to 95 percent; as the chromia content increases, the performance also increases. Therefore, zoning of the refractory lining in these furnaces is critical.

HarbisonWalker International has the expertise to maximize refractory performance, as well as a full range of chrome-alumina materials under the AUREX® and the SERV® families. In addition, the reclamation of the chrome-alumina refractories is critical to reduce the environmental impact and health concerns. HWI utilizes a REUSE program to convert used chrome-alumina refractories to a synthetic chrome-alumina grain that is incorporated into products like RESERV®.
